Among the many updates to the Potterverse these days is the release of Harry Potter and the Cursed Child. The play officially opens with a gala on Saturday in London, but for those of us who can't get across the pond, the script releases soon thereafter.

In anticipation of Harry Potter and the Cursed Child Parts 1 and 2, which drops on Sunday (also author J.K. Rowling's birthday), seven area Barnes & Noble bookstores are having a Countdown to Midnight Party, starting at 8 p.m. Saturday. Locations celebrating include stores in St. Petersburg, Clearwater, Tampa (Dale Mabry and Carrollwood locations), Brandon, Wesley Chapel and Sarasota.

Books-A-Million stores are having a Harry Potter Midnight Release Party starting at 2 p.m. The five greater Tampa Bay area locations are in Lakeland, Brandon, Port Richey, Bradenton and Sarasota.

The special, rehearsal edition script of the play written by Jack Thorne is based on the new story by J.K. Rowling, John Tiffany and Thorne.

The B&N party will feature a special Muggle Wall where customers can share their favorite memories of Harry Potter, and there will also be giveaways. On Sunday, return to discuss the new book and participate in special Harry Potter-themed events and activities at Barnes & Noble.
